4vehicle springs, and it relates es )ccially to" certain improvements incom "ined supporting bolt and lubricator ttor the eye of? the spring.

The object ot' the invention is 'to provide a construction which isetllcient and for less expensive and troublesome to make than thedevices employed hereto-lore.

More specifically, the invention aims to do away with the necessity ofWelding to or or otherwise lor-nung on the bolt shank by the expensiveprocesses employed heretofore a bolt head and lubricating cup, and toprovide a construction wherein an ordinary bolt may be employedtosupport the spring and to convey to the spring eye, lubricant from aclamping nut which is orined to serve as a lubricant cup.

My invention tney be briefly summarized as consisting in certain noveldetails or" constructionV and combinations and arrange' ments of partswhich will be described in the specification and set forth in theappended claims,

ln the dra-Wing, Figure l is a side View A oit' the shackle and the endsoit two springs supported and coupled together by the shackle; Fig. 2 isa sectional vienT solisten tially along the line 2--2 el? lig. l,looking in the direction indicated by the arrows; Fig. 3 is a verticalsection throukl, the lower part of a shackle showing modification of myinvention.

Reference is now l;

two springs 'il end l2, which a so-called elliptic or tlirec-- springJfor vehicles. ',he main 1s ogeneral construet?L n i" a pair ol swinginglinks 1.3,

a pair or clamping bolts 142, one passing betiyeenthe upper ends of thelinks and through an eye 11*l formed on the endk ci spring lil, the eyelbeing located. between the links, and the 'other bolt passing throughthe lower ends of the links and through an eye l2 at the vend or springlf2, which is similarly situated between the tivo links.

li/ly invention resides particularly in the bolt which enters into thecombination oit parts constituting the spring support or coupling',together with means for provid-- ing lubrication for the bearingsurfaces of lthe bolt shank and spring eye. -eOrdinarily 'inconstructions of this type, provision is mede tor lubrication byproviding on the holt shank a special head which is designed to serve asa lubricant cup and is usually Welded to the shank or otherwise formedby a process equally or more expensive. ln accordance with my invention,l utilize a bolt of ordinary construction which Vis relativelyinexpensive to manufacture and which includes a shank 14a and the usualholt head 14h, forming one of the clamping abutments for theconstruction. The opposite end of the bolt shank is threaded and on theportion which extends beyond the adjacent link 13, l provide a specialclampingr nut 14e. This nut has next to the link a portion whichcoperaties with the head to crrn the' two clamping abutinents betweenwhich the links and the spring eye are clamped. rl`he nut also has anextension which serves as aA lubricant cup, and is threaded on thcexterior to receive a cap ill forming a closure tor the cup. Thelubricant is conveyed from the cup to the lesring surfaces by' means ofa duct lee, which' extends axially from the threaded 'ende of the shankto a point substantially inidiva'y between the links and thencelaterally tothe surface of the shank, so as to convey the lubricant tothe bearing surfaces. 'lhe construction at one end of the shackle isgn'eleralil'r the same as r,at the other end, :is illustrated clearly in2. This siniyle shackle construct-ion is equally eflicient and .in manycases more efficient than the prior constructions, butA is tar lessexpensive an the latter.

in the shackle, some means should be prov' "ed lor preventing thelooseningof the bol s and nuts, and in the forni shoivn in this isaccomplished by threading' the bolt openings in one of the links, and byextending the threaded portions of the bolt threaded connection withthis link, in which l through the openings in both links and the nut 16cis prevented from turning by a nut lock 17 in the form of a washerbetween the nut and the adjacent link l5, which washer has aportion bentlaterally over one of the Hatte/ned faces of the nut and another portionbent over the end of the link to prevent the nut from turning. In thisconstruction, the nut, together with its assoeiated cap, serves as alubricant cup, and the lubricant is conveyed inwardly 'and laterallyfrom the end of the shank, as in-the case first described.

Having thus described my invention, what I claim is:v

1. In combination, a vehicle spring having ari eye at its end and asupport for the spring comprising two side members which receive the eyebetween them, a bolt passing through the side members and through theeye, said bolt having a shank and two clamping abutments consisting of ahead at one end of the shankand a nut at the other end thereof, theshank having a duct eX tending axially from the end provided with thenut, the said nut having an annular threaded part and a cap screwed ontosaid part of the nut, said nut and cap constituting a. lubricantcontainer of which the cap forms one part and the nut another part.

:2. In combination with a vehicle spring having an eye at its end, aspring-securing and lubricating bolt having a shank passing through theeye and provided at one end with an integral head and at. the other endwith a nut, and the said shank having a duct extending axially from theend provided with the nut, said nut having a part'shaped to accommodatea wrench and ,having a circular exteriorly threaded part,a`nd a capadjustably screwed onto said threaded part and forming with the nut atwo-part lubricant container of which the cap forms one part, and thenut the other part.

In testimony whereof, I hereunto aiiix my signature in the presence oftwo witnesses.
